CONDUIT COUPLING.

Application filed April 29, 1920.

To all whom it may concern:

Be it known that I, Josamr F. RAMBO, a citizen of the United States,residing at Pomona, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in ConduitCouplings, of which the following is a specification.

This invention relates to electrical apparatus and particularly toconduit connections, and has for its ob'ect to provide an improvedcoupling for t e connection and support of a conduit or pipe to a gas,water or other convenient sup orting part, and the invention consists ofthe construction, the combination and in details and arrangement of theparts, embodiments of which are illustrated in the accompanying drawingsand described and claimed herein.

Figure 1 is a side elevation of a form of connection between relativelyright angular parts.

Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is a transverse section on line 3-3 of Fig. 1.

Fig. 4 is a side elevation of a 45 joint connector.

Fig. 5 is a side elevation of an elbow type of connector.

Fig. 6 is a transverse section through a modified form of. theinvention.

In the illustrated embodiment of the. invention a ground wire 2 is shownas having one end looped or wrapped around a water, gas, or other groundpipe 3, and for the purpose of protecting the ground wire 2 it isincased in a conduit or pipe 4 which it is desired to securely supportwith relation to the stationary or fixed pipe 3.

To that end the invention consists of a conduit connector or couplinpreferably, made of separable sections in t is case halves indicated at5 and 6, these being right and left hand members. In Figs. 1 and 2 theconnector halves are provided with semicylindrical rtions 7 and 8rovided with an intermediiite rid e or bea 9 and internally concaved toorm an arcuate seat 10 embracing the loop 2 of the conductor wrappedaround the pipe 3. The arcuate sections 5 and 6 of the connector areeach shown as provided with a diametrically alined and laterallyprojecting extension indicated at 11, these to embrace the adjacent endof the conduit 4.

The sections 5 and 6 when assembled may Specification of Letters Patent.

be securely detachably looked as by a bolt 12 passing throughoverlapping ears or lugs 1-3 formed on one side of the sections 5 and 6,and on the op osite sides of the extensions 11 there may also beprovided lugs or cars 14 through which may be passed fastening means asscrews or bolts 15. Preferably the ears 14 are countersunk in theiradjacent faces as at 14 to receive interposed terminals of otherconductors indicated at C.

In Fig. 4 the connector is shown as of slightly modified form to connecta conduit 4 that is dis osed obli uely to the length of the pipe 3. nFig. 5 t e connector is shown as of such shape as to provide for theconnection of a conduit 4 extendin parallel to the pipe 3. In this casethe si e extensions 11 are shown as elbows of 90 bend.

In the modification of the invention illustrated in Fig. 6, the arcuatesections 5' and 6' meet in the plane of the axis of the pipe 3, thelower section 6' bein provided with an extension 11' having t readedengagement with a conduit or pipe 4 as shown at 20. The arcuate sectionsare provided with lugs or ears 14 through which may be passed fasteninmeans as screws or bolts 15.

It wi i be understood that this modified form of the invention may alsobe formed to connect a conduit 4 that is disposed obliquel to the lengthof the pipe 3, or which exten s parallel to the pipe 3 by suitablybending the extension 11 From the above it will be seen that I haveprovided a simple inexpensive, practicable. durable and readily attachedand detached connector for effecting the connection of a conduit of aconnecting ground line of a su orting and convenient pipe as 3.

arious changes may be made without departing from the spirit of myinvention as claimed. K

I claim:

1. The combination with an electrical conduit pipe inclosing a groundwire, of means for connecting said conduit in contiguous and fixedrelation to a grounding pi c; said means comprisin a sectional coup inattachable to the said conduit and the sai pipe and having fasteningdevices for securing the parts assembled; the sections having interiorseats to receive the ground conductor.

2. The combination with an electrical conduit pipe including a groundwire, of means for connecting said conduit in contiguous and fixedrelation to a grounding pi e, said means comprising a sectional couplingattachable to the said conduit and the said pipe and having fasteningdevices for securing the parts of the sectional coupling and forattaching electrical conductor Wires, the sections of the couplinghaving entire means for engaging the ground Wire within the conduitpipe.

3. The combination with an electrical conduit pipe inclosing a groundwire, of means for connecting said conduitin contiguous and fixedrelation to a grounding ipe, said means comprising a sectional couplingattachable to the said conduit and the said ipe and having fasteningdevices for securmg the parts assembled, the sections of the couplinghaving means for engaging the ground Wire.

In testimony whereof I have signed my 20 JOSEPH F. RAMBO.
